ZnSe sensor lense is widely used in CO2 laser cutting
,marking,drilling,other laser system of industrial, which has low
absorption and withstand high laser power.The coating layer of ZnSe
lense is solid.The trasmission of it can reach 67 % in 10.6 micron.

We do the optimization design according to diffration and
aberration and then show the products that have actual focus spot
size in the same focal length. We can produce the products upon
your requirement.

We take the import ZnSe which is yellow transparent multi-crystal
to be coating. Its trasmittance is 0.5-15μm. It is made in chemical
vapor deposition method,which have little inclusions and low
obsorption. Its has feature of low scatter loss. It is the best
substrate that can make IR lenses to use in CO2 high power laser
system because of low absorption in 10.6μm.
